We're dividing 11887738 by 742 
The aim is to understand the frequency of 742 in 11887738.

Let's proceed to step 1:
742 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 742

Going ahead to step 2:
11 divided by 742 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 742

Moving on to step 3:
When dividing 118 by 742, we get 0 with a remainder of 118.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 118 and we're left with 118.
Grab the next digit (8) from the dividend, add it to 118, then carry on: 1188 / 742

Advancing to step 4:
742 goes into 1188 1 times with a remainder of 446.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 446 after subtracting 742 from 1188.
Fetch the next digit (7) from the dividend, attach it to 446 and continue: 4467 / 742

Step 5:
742 goes into 4467 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 4452 away from 4467, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 742

Let's proceed to step 6:
If we divide 157 by 742, we get 0 and a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
If we take 0 away from 157, we end up with 157.
Append the next digit (3) from the dividend to 157 and continue with: 1573 / 742

Going ahead to step 7:
If we divide 1573 by 742, we get 2 and a remainder of 89.
Put 2 as the next digit of the answer. 
Result so far: 1602.0
Deduct 1484 from 1573 and we're left with 89.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 742

Going ahead to step 8:
The number 742 fits into 898 1 times, leaving a remainder of 156.
Use 1 as the next digit of our solution. 
Result so far: 16021.0
The remainder is 156 after subtracting 742 from 898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 9:
742 can be fit into 1560 2 times, resulting in a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 16021.2
Deduct 1484 from 1560 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
742 can be fit into 760 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 16021.21
The remainder is 18 after subtracting 742 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
If we divide 180 by 742, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 16021.21
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
1800 divided by 742 is 2 with a remainder of 316.
The number 2 becomes the next digit in our result. 
Result so far: 16021.2102
The remainder is 316 after subtracting 1484 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 13:
When dividing 3160 by 742, we get 4 with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 16021.21024
Subtracting 2968 from 3160 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
The number 742 fits into 1920 2 times, leaving a remainder of 436.
The number 2 becomes the next digit in our result. 
Result so far: 16021.210242
If we subtract 1484 from 1920, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 15:
4360 divided by 742 is 5 with a remainder of 650.
Write down 5 as next digit of the result. 
Result so far: 16021.2102425
Subtract 3710 from 4360 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 16:
If we divide 6500 by 742, we get 8 and a remainder of 564.
Put 8 as the next digit of the answer. 
Result so far: 16021.21024258
Subtract 5936 from 6500 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

The final outcome is 16021.21024258, with a leftover of 5.64e-07.
